Answer 1

var myDate = new Date();
var cyear = myDate.getFullYear();
var cmonth = myDate.getMonth();
var cday = myDate.getDate();
var hours = myDate.getHours();
var minutes = myDate.getMinutes();
var seconds = myDate.getSeconds();
var startDate, endDate;
var cut;
var space = 5;
var all = '[{';
cmonth = cmonth + 1;
if (cmonth < 10) {
    cmonth = '0' + cmonth;
}
if (cday < 10) {
    cday = '0' + cday;
}
var created = cyear + '-' + cmonth + '-' + cday;
var shift = 'Y';
if (shift == 'B') {
    startDate = created + ' 08:30';
    endDate = created + ' 20:30';
} else if (shift == 'Y') {
    cday = myDate.getDate() - 1;
    created1 = cyear + '-' + cmonth + '-' + cday;
    startDate = created1 + ' 20:30';
    endDate = created + ' 08:30';
}

// Rest of your code...

var all1 = all;
